This is because the object's velocity can change direction in two dimensions without necessarily changing its magnitude, leading to acceleration along curved paths. Projectile motion, on the other hand, involves acceleration only in the vertical direction due to gravity while the horizontal velocity remains constant.
Gravity
Two-dimensional motion that is not always projectile motion would be circular motion, where an object moves in a circular path. Two-dimensional motion that is not projectile motion and does not accelerate the object could be uniform circular motion, where the speed is constant but the direction changes.
Gravity
Circular motion is a type of two-dimensional motion that is not always projectile motion. In circular motion, such as a car driving around a curve or a satellite orbiting a planet, the object is constantly changing its direction without necessarily being launched upwards. This motion can involve acceleration due to the changes in velocity direction.
No, a projectile is not always in free-fall. A projectile is any object that is thrown or launched into the air and is affected by gravity. While a projectile is influenced by gravity and follows a curved path, it may not necessarily be in free-fall if other forces are acting on it, such as air resistance or propulsion.

Assuming negligible air resistance, the acceleration of a projectile near the Earth's surface is always the gravitational 9.81 m/sec/sec downwards, regardless of where in the trajectory the projectile is.
The two forces acting on a projectile in motion are gravity, which always acts downward, and air resistance, which opposes the projectile's motion through the air. Gravity causes the projectile to follow a curved path, while air resistance slows down its movement.

False. A projectile is an object that is thrown or launched into the air and has a parabolic trajectory. A cannonball rolling down a slope is not considered a projectile because it is not launched into the air.
No. It always indicates that the object is not accelerating.
An object in circular motion is always accelerating because its direction is constantly changing even if its speed remains constant. This acceleration is called centripetal acceleration and is directed towards the center of the circle in which the object is moving.
